Abstract: Neste trabalho objetivou-se avaliar o efeito de concentrados à base de silagens de gr os de milho puro ou com adi o de gr os de girassol ou ureia sobre a composi o, desempenho e rendimento de carca a de cordeiros Hampshire Down- sem ra a definida (SRD), terminados em confinamento. Foram avaliados três tratamentos sendo: silagem de gr os de milho (SGM); SGM com adi o de gr os de girassol (SGMG); SGMcom adi o de ureia (SGMU). Utilizaram-se 24 cordeiros machos inteiros, com peso médio inicial de 23 kg, distribuídos nos tratamentos (8 animais tratamento-1). Após o abate, as carca as foram pesadas para obten o do peso da carca a quente (PCQ) e armazenadas emcamara frigorífica a 4°C, por 24h para obten o do peso da carca a fria (PCF). O peso vivo médio ao abate foi de 31,1 kg com ganho médio diário (GMD) de 0,164 kg. O PCQ médio foi de 13,4 kg com rendimento médio de 43,13%, enquanto o PCF foi de 12,8 kg. N o houve efeito dos tratamentos sobre estas variáveis, evidenciando que a qualidade dosconcentrados foi semelhante. A silagem de gr os de milho associados com gr os de girassol ou ureia, na alimenta o de cordeiros, n o influencia as variáveis quantitativas da carca a, sendo recomendado seu uso na formula o de concentrados. Effect of concentrated compounds either with unmixed corn silages or with sunflower or urea on the composition, performance and carcass yield of Hampshire Dow and without definite race lambs finished in feedlots was evaluated. Three treatments were evaluated: corn grain silages (CGS); CGS with sunflower grains; SGS with urea. Twenty-four male lambs, mean initial live weight of 23 kg, allotted in treatments (8 animals treatment-1), were employed. After slaughter, carcasses were weighed for hot carcass weight (HCW) and then refrigerated at 4°C for 24 hours for cold carcass weight (CCW). Mean live weight at slaughter was 31.1 kg with mean daily gain (MDG) of 0.164 kg. Mean HCW was 13.4 kg with a mean yield of 43.13% while mean CCW reached 12.8 kg. Since treatments did not affect variables, quality of concentrates was similar. Corn grains silages with sunflower grains and urea in lamb feed failed to affect the carcass’s quantitative variables and their use is recommended for concentrates.

Abstract: Objetivou-se avaliar o desempenho e a qualidade do leite produzido por vacas da ra a Holandesa no ter o final da lacta o, alimentadas com silagens de grama estrela com aplica o de inoculante ou uréia em rela o à silagem de milho. Foram avaliadas silagens de grama estrela com aplica o de aditivo enzimo-bacteriano na dosagem de 80 g deinoculante/tonelada, uréia na dosagem de 7 kg t-1 e silagem de milho. Para avalia o do desempenho produtivo e digestibilidade foram utilizadas seis vacas da ra a Holandesas com peso médio de 480 kg distribuídas em delineamento (duplo) quadrado latino (3 x 3). Asdigestibilidades da MS, PB e FDN foram maiores para a silagem de milho. O fornecimento de silagens de grama estrela com aditivo e com uréia n o interferiu na produ o e qualidade do leite, mostrando-se como alternativa para sistemas de produ o animal com base emvolumosos conservados mediante a análise econ mica da substitui o da silagem de milho. The study aimed to evaluate animal performance and quality of milk from Holstein cows during the final third period of lactation fed stargrass silages supplied with inoculant or urea in relation to corn silage. Stargrass silages with enzymatic-bacterial inoculant (80 g of additive/ton of silage), urea supply (7 kg t-1) and corn silage were evaluated. Six Holstein cows with an average body weight of 480 kg were allocated in a double Latin square design (3 x 3). Corn silagepresented the highest values of DM, CP and NDF digestibility when compared to stargrass silages. Supplying Holstein cows with stargrass silages with additive and urea did not promote any effect on production and milk quality. Thus, it can be an alternative in animalproduction systems based on conserved roughage, depending on economical analysis for the replacement of corn silage.

Abstract: Objetivou-se avaliar a composi o química e as perdas totais de MS na silagem de soja colhida em diferentes estádios reprodutivos. O trabalho foi dividido em dois períodos experimentais, safras de 2005 e de 2006. Foram determinados quatro estádios reprodutivos (R3, R4, R5 e R6) como tratamento no Experimento I (2005) e três estádios reprodutivos (R5, R6 e R7) no Experimento II (2006). O material foi acondicionado em silos experimentais de PVC, sendo as amostragens efetuadas na abertura do silo (60 dias após a ensilagem) para avaliar a composi o química. No Experimento I, houve diferen as (p < 0,05) nos quatro estádios reprodutivos para os teores de MS, CZ, MO, PB, LIG, EE e CT. N o se verificou diferen a (p > 0,05) para os valores de FDN, FDA, NIDN, NIDA, CEL, CHO e pH. No Experimento II, as silagens n o apresentaram diferen as (p > 0,05) para o teor de MS, CZ, MO, PB, FDN, FDA, EE e CHO em fun o do estádio de desenvolvimento da cultura de soja. Os valores de pH, CE e CT das silagens apresentaram diferen as (p < 0,05) entre os estádios reprodutivos. O avan o do estádio reprodutivo altera o valor nutricional da silagem da planta inteira de soja. O déficit hídrico influencia negativamente o desenvolvimento adequado dos gr os de soja,ocasionando prejuízo especialmente em rela o ao valor proteico da silagem. This trial was carried out to study the chemical composition and total DM losses of soybean silage at different reproductive stages. The work was divided in two evaluation periods: the 2005 and 2006 harvests. Four reproductive stages were determined (R3, R4, R5 and R6) as treatments in trial I (2005) and three reproductive stages (R5, R6 and R7) in trial II (2006). The material was conditioned in PVC experimental silos, and the samples were taken at the time thesilo was opened (60 days after ensilage) to evaluate the chemical composition. In trial I, there were differences (p < 0.05) in the four reproductive stages for DM, ash, OM, CP, LIG, EE and BC. No differences were observed (p > 0.05) for NDF, ADF, NDIN, ADIN, CELL, total carbohydrate and pH. In trial II, the silages did not present differences (p > 0.05) for DM, ash, OM, CP, NDF, ADF, EE and total carbohydrate in function of the soybean harvest stage. The pH values, electric conductivity and buffering capacity of the silages were different (p < 0.05) among the reproductive stages. The advance of reproductive stage changes the nutritional value of whole-plant soybean silage. The water deficit adversely affects the suitable development of soybeans, where the protein value of silage is penalized.

Abstract: The shunt portosystemic or portosystemic deviation (PSD) are unique or multiples vascular communications between the systemic circulaton and the portal circulation, that permit blood flow reaches the circulatory system without first passing trhought the hepatic metabolization. May be acquired or congenital and can also be classified as intrahepatic located within the liver or extrahepatic located outside the liver parenquima. The acquired form is usually associated with intra-hepatic disorders. They usually suggest tortuous vessels that communicate with the caudal vena cava in the region of the left kidney. The congenital form is associated with genetic lineage and one of the most affected is Maltese breed. This case report describes the diagnostis and treatment of a eight year-old female Maltese dog presenting extrahepatic Portosystemic Shunt. The patient showed signs of hepatic encephalopathy, such as restlessnees, weakness, deambulation, head tremor and impaired visual. Complementary exam demonstrated: postprandial glicemia near the lower limit of reference, alkaline phosphatase (ALP) and alanine aminotransferase (ALT) increased and hipoalbuminemia. Ultrasonography revealed the presence of vesical calculus and bilateral kidney, liver decreases and increased echogenicity, gallbladder with anechoic content and high cellularity may suggest liver/ colangiohepatopatia and extrahepatic DPS was detected. The use of Doppler assisted in identifying the location of the bypass communication and the turbulence detecting the extrahepatic DPS. Protein-restricted diet and antibiotic therapy with amoxicillin achieved good results. The clinical treatment was decided make only the clinical and maintain the quality of life of the patient. Objetivou-se avaliar a degradabilidade ruminal e a taxa de degrada o in situ da matéria seca (MS), da proteína bruta (PB) e da fibra em detergente neutro (FDN), dos fenos de alfafa e Tifton-85 e da silagem de milho. Foram utilizadas três vacas fistuladas no rúmen, adaptadas às dietas por um período de 15 dias e incubadas com as amostras em sacos de náilon por três dias. Os tempos de incuba o utilizados foram: 0, 2, 6, 12, 24, 48 e 72 horas. Após a remo o, os sacos foram lavados ligeiramente em água corrente e em seguida congelados até a completa remo o dos demais. A degradabilidade efetiva (DE) da matéria seca, da proteína bruta e da fibra em detergente neutro do feno de alfafa mostrou-se (P<0,05) superior ao feno de Tifton-85 e a silagem de milho. As degradabilidades potenciais (DP) e efetivas (DE), para taxa de passagem de 5 e 8

Abstract: The objective of this work was to evaluate the effects of corn (Zea mays L.) silage and elephant-grass (Pennisetum purpureum Schum) silage on the nutrition of cows during lactation, over some of the blood constituents (glucose, triglycerides and urea). The treatments were three silages (corn silage, elephant-grass silage with bacterial inoculating, elephant-grass silage with enzyme-bacterial inoculating). Nine Holstein cows, with a medium weight of 520 kg, were distributed in experimental delineation of simultaneous triple Latin square. The blood glucose rates were considered normal, independents of the silage used. Concerning the triglicerides levels, it was verified that they are below normal to the different silages. One of the reasons would be the low fat level on the diet. The blood levels of urea observed on the three treatments are considered normal. There was not significant difference among the different kinds of silage in relation to the blood levels of urea, glucose and triglycerides. O objetivo deste trabalho foi avaliar os efeitos do fornecimento de silagem de milho (Zea mays L.) e silagem de capim-elefante (Pennisetum purpureum Schum) na alimenta o de vacas em lacta o, sobre alguns dos constituintes sangüíneos (glicose, triglicerídeos e uréia). Os tratamentos foram três silagens (silagem de milho, silagem de capim-elefante com inoculante bacteriano, silagem de capim-elefante com inoculante enzimo-bacteriano). Foram utilizadas nove vacas da ra a holandesa, com peso médio de 520 kg, distribuídas em delineamento experimental de triplo quadrado latino simultaneo. As taxas de glicose sangüínea das vacas foram consideradas normais, independente do volumoso utilizado. Em rela o aos níveis de triglicerídeos, verificou-se que est o abaixo do normal para os diferentes volumosos. Uma das raz es seria o baixo nível de gordura na dieta. Os níveis sangüíneos de uréia observados nos três tratamentos s o considerados normais. N o houve diferen a significativa entre os volumosos em rela o aos níveis sangüíneos de uréia, glicose e triglicerídeos.

Abstract: It was aimed to evaluate the ruminal degradability, and the fractioning of carbohydrates, as well as of the nitrogen fractions of triticale silages in singular culture or in mixtures with oats and/or legumes. The treatments had been: triticale silage (X. Triticosecale Wittimack) (ST); triticale silage + forage pea (Pisum arvense) (STE); triticale silage + oats (Avena strigosa Scheb) + forage pea + vetch (Vicia sativa) (STAE). Three castrated bovine Prim’Holstein males had been used, with average live weight of 300 kg, having ruminal cannulas. The incubation times had duration of 0, 6, 12, 24, 48, 72 and 96 hours. Fractions, a, c and ED of the DM of STAE silage was higher (30,33; 0,026 and 45,45%) than others silages. Fraction b of the DM of ST silage was higher (58,45%) than STE silages (45,36%) and STAE (44,37%). In CP the ST silage presented higher fraction (72.12%). For the potentially degradability fraction (b) of CP it was not observed difference among treatments. The degradation rate (c) of the CP was higher for STE silage (0.063%) than ST ensilage (0,012%), however this was similar to the STAE (0,045%). ED of CP was better for STE silage (77,71%). ST silage presented fraction a and b for NDF highest (8,62 and 81,99%) than others silages. The degradation rate (c) of NDF was higher for STAE (0,027%). ED for NDF did not present difference among treatments. ST silage presented the best values for the total carbohydrates (83,97%) than STE (79,87%) and STAE silages (76,77%). STE and STAE silages presented better DM degradability and suggest to be a potential source of non degradable protein in the rumen. The exclusive triticale silage revealed superior with regard to the degradability of fiber fraction, also presenting higher amount of total carbohydrates potentially degraded. O objetivo desse trabalho foi avaliar a degradabilidade ruminal, e o fracionamento de carboidratos, assim como das fra es nitrogenadas das silagens de triticale em plantio singular ou em misturas com aveia e/ou leguminosas. Os tratamentos foram: silagem triticale (X. Triticosecale Wittimack) (ST); silagem de triticale + ervilha forrageira (Pisum arvense) (STE); silagem de triticale + aveia (Avena strigosa Scheb) + ervilha forrageira + ervilhaca (Vicia sativa) (STAE). Foram utilizados três machos bovinos castrados da ra a Holandesa, com peso vivo médio de 300 kg, portadores de canula ruminal. Os tempos de incuba o empregados tiveram a dura o de 0, 6, 12, 24, 48, 72 e 96 h. As fra es a, c e a DE da MS da silagem STAE foram maiores (30,33; 0,026 e 45,45%) em rela o às demais sil

Abstract: O trabalho teve como objetivo avaliar o tratamento do feno de grama-estrela (Cynodon nlemfuensis Vanderyst) com uréia sobre a digestibilidade da dieta em ovinos. Os fenos foram tratados com uréia na propor o de 2, 4 e 6% com base na MS. Os fardos foram colocados sobre uma lona plástica e arranjados em camadas de 16 fardos por tratamento. Após a aplica o da uréia diluída em água, os fardos foram cobertos com lona para armazenagem em condi es herméticas durante 60 dias. Para determina o da digestibilidade, foram utilizados 4 ovinos machos com peso médio de 26 kg. A dieta foielaborada com níveis crescentes de PB (11,78; 13,24; 16,11 e 16,83%) e o delineamento utilizado foi o quadrado latino (4 x 4). A digestibilidade aparente de MS, MO e FDA aumentaram linearmente com o aumento nos níveis de uréia. Observou-se efeito quadrático para FDN, HEM e CEL, com maior digestibilidade para os fenos tratados com4%. Também foi observada resposta quadrática para a PB, com menor digestibilidade para os fenos tratados com 2% de uréia. Conclui-se que o tratamento do feno de grama-estrela com uréia em níveis de 4 a 6% melhora o valor nutricional da forragem. This study was carried out to evaluate the effect of Stargrass (Cynodon nlemfuensis Vanderyst) hay treated with urea in the diet digestibility fed to sheep. Hays were treated with 2, 4 and 6% of urea in dry matter. Stargrass bales were placed on a plastic tent, in two layers of sixteen bales per treatment. After adding the urea diluted in water, the bales were covered with tent to allow a hermeticstorage condition during the 60 days. To determine the digestibility coefficient, four lambs (26 kg) were used. Diet was calculated with increasing levels of CP (11.78, 13.24, 16.11 and 16.83%) and a Latin square design (4 x 4) was used. DM, OM and ADF apparent digestibility increased linearly with growing levels of urea. There was a quadratic effect to the NDF, hemicellulose and cellulose digestibility, with higher values being observed for hay treated with 4% of urea. CP digestibility also showed a quadratic effect, with lower values being observed for hay treated with 2% of urea. It was concluded that ammoniations of Stargrass hay with 4% to 6% of urea presents a better nutritional quality of forage.

Abstract: The characteristics of lamb meat are influenced by a series of factors, among which the testicular hormone production. In order to estimate the influence on meat characteristics, 24 Suffolk, Ile de France, Santa Inês and Texel crossbred lambs male, in a completely casualised delineation, with three treatments and eight repetitions. All animals were managed in the same way, pasture-raised and fed on native grass, in a Voisin system. The experiment treatments were constituted of non-castrated, castrated and cryptorchid animals. Live weight measurements were recorded at birth, once a month to assess body development and before slaughter. The warm carcass weight at slaughter and the 24 hours post-slaughter weight of the carcass cooled in refrigeration chamber at 5oC were recorded. Also, the weights of the variables related to the carcass were obtained. The results were analyzed using GLM Procedure and the means compared by Tukey’s test at the 5% significance level. No differences in production were found in the components and in the characteristics of the ovine meat and carcass of non-castrated, castrated and cryptorchid lambs raised on pasture land, fed on native grass and slaughtered young. O objetivo deste trabalho foi avaliar os efeitos de diferentes porcentagens de gr os de soja crus, adicionados aos gr os de milho, sobre as características de fermenta o e composi o química das silagens. Os tratamentos testados foram, silagem de gr os de milho com inclus o de 0, 10, 20, 30, 40% de gr os de soja crus. Foram utilizados silos experimentais com capacidade para aproximadamente 12 kg de silagem, sendo que esses permaneceram vedados por um período de 12 meses, quando foram abertos para amostragens e análises químicas. O delineamento experimental empregado foi inteiramente casualizado, com três repeti es por tratamento. A adi o de gr os de soja proporcionou aumento nos teores dos nutrientes (MM, PB, EE) das silagens, sem interferir na qualidade de conserva o das mesmas.
